lMPROVEMENI IN MECHANICAL STRIKERS FOR BLACKSMITHS.

Specification forming part of Letters Patent No. 218,986, dated August 26, 1879; application filed May 13, 1879.

To all whom it may concern.-

Be it known that I, HOWARD H. KING, of Lecompte, in the parish of Rapides and State of Louisiana, have invented certain new and useful Improvements in Mechanical Strikers for Blacksmiths; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The invention relates to a smiths device, consisting of a stationary anvil and adjusta ble frame carrying pedal-hammer; and the novelty consists in the construction and arran gement of parts, as will be more fully hereinafter set forth.

In carrying out my invention I employ a proper base, upon which is permanently formed or removably secured the operating devices.

A rigid block furnishes support for the anvil, which may be of any desirable form and construction.

A frame having a pivoted slotted arm is secured adjustably at the forward end to the anvil-block by thread-bolt and nut or set-screw connection, and equivalent adjustable securin g devices at the rear operate in slots in bracestandards, as shown.

From a rear cross-bar a threaded upright passing through a cap-bar and governed by crank-nut or other set-screw, allows the adjustment of the rear of the frame at will.

Journaled in the upper ends of the main standards of the adjustable frame is a shaft carrying rigidly at the center, between the standards, the hammer-arm, and at one end an arm which connects by a strap with a reverse spring, or, in other words, a spring exerting a constant force to hold the hammer out of contact with the'anvil, and at the opposite end a curved arm which, by a link, adj ustably connects with a pedal-lever connected pivotally and properly braced to the adjustable frame.

The hammer is foreedinto contact with the anvil by means of the pedal-lever, the spring exerting a constant force'in the opposite direction, and the construetion'is such that when the depression is removed from the treadle the spring forces the hammer back until it stops at rest, supported by the frame.

Referring to the drawings, A represents the base, and B the anvil-block, perforated at b to receive a bolt and set-nut, b, said block B carrying the anvil O, of any desired form and material. D Drepresentbrace-standards, having slots d.

An adjustable frame, E, consisting of approximately horizontal side bars and properly-braced standards E, is vertically adjustable at the forward end by means of a pivoted slotted arm, F, which operates in connection with the securing device I), and at the rear by set-rods operating in the slots (Z of the brace-standards D, as shown.

A rod, G, having threaded extension 9, is secured to frame E, and, governed by a cranknut, G, allows the vertical adjustment of the rear of the frame, and set-nuts w operate to secure the adjustment at any desired point, as shown.

H represents a shaft journaled in the standards E, carrying rigidly the hammer-arm H The arm I, which, by straps I, connects with spring J, is secured at J to the frame E. Also rigid with this shaft is a curved arm, H, which extends backward, upward, and forward in such proper curve as to afford a partial spring to the same, and this arm, by a link, K, connects with a pedal-lever or treadle, L, the connection being adjustable by means of the devices is Z, as shown.

It will be observed that the hammer is brought into forcible contact with the anvil by means of the treadle acting through the link K and curved arm H, and that said arm,

by its spring, relieves the operator from the jar were the same rigid and ungiving. The spring retrieves the hammer, and the stroke is readily adjustable.

I claim as new anddesire to secure by Letters Patent- 1.
